JB-Ex-20 is a multiple entry power connection junction box. Designed to connect power, via armoured cable, 100 - 254 Vac, to three RRaychem FMT and FHT constant wattage heating tapes, polymer insulated heating tapes or mineral insulated heating tapes. It can be mounted to a pipe or wall mounted and is approved by PTB for use in hazardous areas

JB-Ex-20 integrates the functions of both connection kits and insulation entries. The rugged stand protects the heating cable and allows for up to 100 mm (4") of thermal insulation. The core sealing boot does not require a heat gun or torch for the installation (no hot work permit necessary). The non-curing sealant (silicone free) in the boot allows easy installation and facilitates maintenance.

Innovative CAGE CLAMP® terminals from WAGO provide fast installation and safe, reliable, maintenance free operation.
